A heat-conducting cavity 10 is formed inside the base 11. The multiple support blocks 12 are all disposed on the base 11 and protrude upward from the base 11. The multiple support blocks 12 are spaced apart along the periphery of the base 11. The heat-conducting baffle 2 is installed on top and covers the heat-conducting cavity 10. The heat-conducting baffle 2 and the base 11 enclose a liquid-holding tank 200 with an upward opening. A flue gas passage 100 is provided between the heat-conducting baffle 2 and the base 11. The outside of the support structure 1 is connected to the bottom of the heat-conducting baffle 2 through the flue gas passage 100.

[0063] The pot support assembly provided by this utility model, by setting a heat-conducting baffle 2 in the heat-conducting cavity 10 inside the support structure 1, forms a liquid-collecting tank 200 between the heat-conducting baffle 2 and the support structure 1, thereby catching the overflow during the cooking process and preventing the overflow from flowing into the burner 5 located below the pot support assembly, thus preventing the burner 5 from extinguishing the flame. Users can directly remove the pot support assembly to pour out the overflow in the liquid-collecting tank 200 for cleaning. In addition, the heat-conducting baffle 2 can also transfer the heat from the burner 5 below to the bottom of the pot without affecting the cooking process. The heating of the cooking pot has the advantages of simple structure and easy cleaning. At the same time, by setting a smoke exhaust channel 100 between the heat-conducting baffle 2 and the support 11, the high-temperature flue gas generated by the burner 5 located below the pot support can be smoothly discharged to the liquid tank 200, and then act on the bottom of the cooking pot to further heat the bottom of the cooking pot before being discharged outside the pot support through the gap between two adjacent support blocks 12. On the one hand, it facilitates the discharge of high-temperature flue gas, and on the other hand, it can also utilize the high-temperature flue gas, thereby improving the thermal efficiency of the gas stove.

The connecting portion 31 is disposed on the lower side of the outer end of the connecting ring 13 and is connected to the connecting ring 13. The second snap-fit ​​portion 32 extends downward vertically. Both the second snap-fit ​​portion 32 and the first snap-fit ​​portion 33 are located on the lower side of the inner end of the connecting ring 13. The inner end of the connecting ring 13 and the heat-conducting baffle 2 form a liquid-holding groove 200. The first snap-fit ​​part 33, the second snap-fit ​​part 32 and the inner end of the connecting ring 13 form an inward-facing snap-fit ​​groove 300. The outer end of the heat-conducting baffle 2 is snapped into the snap-fit ​​groove 300, thereby realizing the installation of the heat-conducting baffle 2 on the connecting ring 13. At the same time, since the connecting ring 13 is located on the upper side of the outer end of the heat-conducting baffle 2, the connecting ring 13 and the heat-conducting baffle 2 can form a liquid-holding groove 200 to facilitate liquid holding, which has the advantages of simple and compact structure.

[0067] Optionally, the connecting ring 13 also includes a perimeter 132 disposed on the outer or inner perimeter of the connecting ring body 131. The perimeter 132 protrudes upward from the connecting ring body 131. By providing the perimeter 132, the depth of the liquid holding tank 200 is further increased, so that the liquid holding tank 200 can hold more overflow liquid.

[0068] Optionally, the support 11 includes a base plate 111, a top enclosure plate 112 disposed on the upper side of the base plate 111, and a bottom enclosure plate 113 disposed on the lower side of the base plate 111.

[0069] Optionally, the support block 12 is disposed on the top plate 112 and connected to the connecting ring 13, thereby achieving a fixed connection between the connecting ring 13 and the support 11, resulting in a simple structure. Of course, in other embodiments, the support block 12 may not be connected to the connecting ring 13, and the connecting ring 13 may be connected to the inner side of the base plate 111 through spaced connecting blocks, provided that the spaced connecting blocks can form a first smoke exhaust channel 101.

[0070] Optionally, the support 11 further includes a reinforcing plate 114. The base plate 111 is a curved panel that is bent outward from the center. The reinforcing plate 114 is disposed on the inner side of the base plate 111. The bottom end of the reinforcing plate 114 is connected to the bottom surrounding plate 113.
